Codenamed "The Knave", Arelcchino is a master of control and manipulation. She is a chameleon, capable of adapting to various situations and personas as needed to achieve her goals within the Fatui and the greater world of Teyvat. She views her ability to maintain a graceful and cordial front while hiding her true intentions as a sign of her intelligence and strategic thinking. Arlecchino is also capable of emphasizing her loyalty to the Tsaritsa, at least as far as it aligns with her interests.
